To all whom it may concern: 7

Be it-known that I, F REDERIGK W. Wane FIELD, .ztcitizen of the United States, and a resident of Vermilion, county of Erie, and State of ()hio, have invented a new and useful Improvement in Convertible Direct or Indirect Lighting Fixtures, of which the following is a specification, the principle of the invention beingherein explained and 1c the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements relate to a convertible direct or indirect lighting fixture 15 for attachment to a suitable fixture support depending from a. ceiling or wall. llhe present popularity of the indirect lighting system has made it desirable to provide fixtures which are suitable for either the direct or indirect method and which can, without change, be assembled for use in either sys tem. The present invention supplies a device for this purpose and one which When used in either system is convenient to asse11ibleaud neat in appearance.

To the accomplishment of these and related ends said invention then consists of the'means hereinafter fully described and particularly pointed out in. the claims.

The annexed drawings and the following descriptions set forth in detail certain mechanism embodying the invention, such dis- -i closed means constituting, however, hut one .oi' various mechanical forms in which the 'principle ol the invention may be used.

Figure l is a side elevation showing my invention as attached to a fixture support as an indirect light, showing in dotted lines the reflector when swung down into a lower 4 positionyl ig. 2 is a section on the line 22 in Fig. 1; Fig. 3 is a central vertical section through the reflector; Fig. 4 is a view similar to Fig. 1 but showing the reflector when connected to the support for use as a direct reflector; Fig. 5 is a. section on line 5--5 in Fig. 4; and Fig. 6 is a View of the supporting means.

In Fig. i 1 there is shown I a canopy 1 which will be attached tea "ceiling by means of a crowfoot or. other connection (not shown) attached to the canopy within the same and fixture support 2 suitably at- 1 tached'to the canopy and extending downward therefrom. At the lower end of the fixture support 2 thereis attached a: receptacle 3 in which is carried a lamp receiving socket (not shown).- The use of these parts is well known as they are used in almost all. depending fixtures for the purpose of inclosing the electrical wires and socket, and

their use in the present-connection may be taken as merely illustrating one desirable term of such element.

The reflector which forms an essential part of the invention includes a suitable rim 4, preferably circular provided with a plu rallty of converging 'iraces 5 which are at tached at their adjacent ends to a second and smaller rim Between the hraces there is adapted to be received a reflector: which is preferably of concavo-eonvch shape This reflector may he of a suitehjly enameled metal or of'glass or similar mate-' rial, and its concave surface must have certain reflecting properties, although the 're- 7 doctor itself will generally be opaque. The

p the rim 6 is provided with bayonet slots 13 for the purposes to be referred to herein after. i

The reflector is maintained within the lorpces by reason of the bent over ends id of the latter, within which the reflector is held. On the outside of the rim i, preferahly opposite each of such braces, there is mounted a loop or lug 15 to which is pivotally attached a closed loop 16. Any desired number of these loops may be provided al though three will ordinarily be suilicient. When it is desired to use the reflector in the indirect way it is disposed with its concave side facing upward and is maintained a suitable distance beneath the receptacle, in which is held a lamp 17, by means of open ended links or hooks 18 which are removably attached to the loops 16 and also to other loops 19, the latter being pivotally at tached to a. collar 20 adjustahl'y secured about the fixture support 2. The proper position for the reflector can be set by the adi ll justment of the collar 20 and a convenient method for operating the lamp is by means of a suitable. cord passing from the receptacle 3 through the bottom of the reflector through the tube 10 where it may be connected to av button switch,' as will bereadily understood. I

The receptacle 3 receives the lamp socket as stated, which is provided with two de pending screws or lugs as shown in Fig. 6 which are adapted to be removably engaged in the bayonet slots 13 formed in the bottom plate 12 of the receptacle or in similar slots formed in a curved collar 21 which is pref-' erably attached to the receptacle to give the samea finished appearance when the reflector is used in the indirect way.

When it is desired to use the reflector in a direct way the cap 11 is removed from the plate 12 by the disengagement of the tube 10 from the cup 8, the two latter members being also removed. The reflector is then po sitioned with its concave side facing downward and the plate 12 is removably engaged with the usual screws which are to be found in the socket in the receptacle, the collar 21 having first been removed therefrom. The open loops 16 are now swung over to the other or convex'side of the reflector and are attached to the loops 19 by the links 18 as before, although it may be necessary to slightly adjust the collar 20 to secure the proper appearance of the links and to permit the same to .serve as braces for the outer rim of the reflector. When used in the indirect way it is often necessary to clean the concave side of the reflector and this maybe conveniently done without removing the same by merely unhooking one of the links 18 from the loop 16 thus permitting the reflector to tilt down in the position shown by dotted lines in Fig. 1, when the reflector may be conveniently cleaned or a replacement made of a lamp into the receptacle. The present de vice is extremely neat in appearance whether used as adirect or indirect reflector, and

may be conveniently assembled as a part of either system without the use of additional tools or equipment.

' Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as re- 'gards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed. v

I therefore particularly point out and distinctly claim as my invention 1. The combination of a depending 'fixture support terminating in a receptacle and being adapted to receive a lamp, a-concavoconvex reflector having an aperture atits center or apex, a plate surrounding such aperture, means attached to said plate and such receptacle and adapted to engage, thereby supporting said reflector with its convex side uppermost, and connecting means, removably. attached to said support and said reflect-or and adapted to brace said reflector when held with its convex side uppermost. 1

2. The combination of a depending fixture support terminating in a receptacle and being adapted to receive a lamp, a. concaveconvex reflector having an aperture at its center or apex, a plate having bayonet slots surrounding such aperture, such receptacle on said-support being provided With lugs adapted to detachably engage in such bayonet slots in said plate, in said reflector,

thereby supporting the latter with its convex side uppermost, and connecting means removably attached to said support and said reflector and adapted to brace said reflector when held with its convex side. uppermost.
